Mummichogs, also known as mud minnows, are a species found in the Chesapeake Bay! The small, brown-green fish can be found in the marshes that surround the bay area. Not only are they found locally, they are also known to live in muddy marshes, tidal creeks and grass flats and along other sheltered shores on the Atlantic coast of North America.

Their individual coloration depends on the sex of the fish. Males tend to be darker than females. The color of the fish’s stripes also varies for males and females. Males have silver vertical stripes, while females have a more neutral coloration.

These resilient fish are able to withstand fluctuations in water quality and temperature, including changes in salinity, low oxygen and they can weather the effects of pollution. Additionally, they consume up to 2,000 mosquito larvae in a single day. This makes these fish extremely useful to naturally control mosquito populations.
